Rural Internet in Caribou ME

February 3, 2012 Leave a comment

Been a while eh?  A while back (June of 2011) I mapped out who could get Time Warner service in Caribou ME and who couldn’t.  I used the 2010 NAIP imagery to digitize all the homes in Caribou.  The homes in the rural areas I verified that they appeared to be used as well as the location where the cable seemed to terminate on the telephone lines.  Furthermore those homes/buildings that were set further back than 300 feet were also excluded since according to Time Warner this is too far to install cable for free.  These findings were compared with the results from to make sure I wasn’t excluding or adding any homes that did/did not have cable.  Based on this methodology Caribou had 3200 building of which 320 did not have access to cable.

By measuring where the cable stopped and which buildings did not have cable I estimated that for the whole city to be serviced an additional 218,726 feet, or 41.43 miles of cable would need to be laid.  At a cost of $20,000 per mile this would equate into a cost of $828,600 for Time Warner.


3D Maps in Dungeons and Dragons Online

September 10, 2010 3 comments

I grew up on Dungeons and Dragons and have loved the imaginary landscapes. Recently I have been playing Dungeons and Dragons Online with my kids. Turbine has created gorgeous and well thought out dungeons but their map system is 2D which makes it difficult to navigate unless you have run the quest multiple times.  I’ve worked on some of the maps to try to make them more understandable with limited success.

To overcome the limitations of a 2D map I have played around with creating a 3D map.  By plotting known locations within the game I can export these quasi X,Y locations into ArcGIS 9.3 along with a 2D picture of the dungeon and plot the layout.  Then by exporting a DWG file into Google Sketchup I can create a 3D environment and add other 3D models to the dungeon.

Using this process I went from a 2D map to a 3D map.  There are quite a few things I can do to improve my results but this is one of my first forays into 3D mapping.

ESRI UC 2010 MGIS Presentation

July 31, 2010 Leave a comment

The ESRI UC 2010 was not as exciting as I remember when I first went there in 2005.  There were a few good discussions but overall it all seemed rather redundant.  However, there were a few notable exceptions. I also presented my Penn State Masters of GIS presentation. So now I have to make a few fixes to the paper and I’m done. I uploaded my presentation as unlisted, just follow the links below if you want to watch. 😀 Yahh!!

ESRI UC Almost Here

June 24, 2010 Leave a comment

Finished up my Masters of GIS project and submitted the paper to ESRI and now working on the Power Point for the conference.  I will be presenting at the ESRI UC on Jul 15 from 3:15 PM to 4:30 PM in Room 29 D, in the Terrain Modeling and Analysis paper session.  My presentation is called, Viewshed Creation: From Digital Terrain Model to Digital Surface Model. 

I will be glad when this is all over. When the papers become available through ESRI I’ll post a link and when my Power Point is done I’ll share it here also.

Viewshed Creation: From Digital Terrain Model to Digital Surface Model

I recently presented to my faculty on my proposed Masters project.  My school does not have a do a thesis (thank goodness) instead we do a project and present at a conference.  Below is my proposed project given to my peers, faculty and my advisor.

ArcGIS Flash Tutorials

January 28, 2009 Leave a comment

Recently a friend asked me how to move a dataset from one feature to another in ArcGIS. I threw together the following tutorials utilizng Wink which is a tutorial and presentation software that creates flash shows. The files are relatively small and they can be put together without too much hassle.

QGIS 1.0.0

January 25, 2009 Leave a comment

On the 10thof this month QGIS 1.0.0 was released, this is very exciting. I first started using QGIS a couple years ago.  However, since I had access to the ArcGIS suite of programs I rarely used QGIS.  Mostly for those times where I needed a portable GIS to visulize shapefiles on a computer that did not have a GIS already installed.

Recently I have had to rely on QGIS and GvSIG as my sole GIS platforms, for various reasons.  While QGIS is not perfect, it is steadilygetting better with each subsequentrelease.  I was planning on sharing my thoughts about version 0.9 but now that 1.0 has been released I think I will go over how this new version compares with previous versions. 

For more information on the current release, the QGIS’ blog  is an excellent resource as is the newly updated manual.
